  • 1. OpenStreetMap NaturNet Plus Počítačem podporované vzdělávání na ochranu životního prostředí
  • 2. NaturNet Plus OpenStreetMap
    • OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world .
    • The maps are created using the data from portable GPS devices, aerial photography, other free sources or simply from local knowledge.
    • Both rendered images and the vector graphics are available for download under a Creative Commons Attribution-ShareAlike 2.0 licence .
  • 3. NaturNet Plus OpenStreetMap
    • OpenStreetMap was inspired by sites such as Wikipedia - a full revision history is maintained .
    • Registered users can upload their GPS track logs and edit the vector data using the given editing tools.
  • 4. NaturNet Plus History
    • OpenStreetMap (OSM) was founded in July 2004 by Steve Coast.
    • In April 2006, a foundation was established with the aim of encouraging the growth, development and distribution of free geospatial data and providing geospatial data for anybody to use and share.
    • In December 2006 Yahoo confirmed that OpenStreetMap could use their aerial photography as a backdrop for map production
  • 5. NaturNet Plus History
    • By August 2008, shortly after the second The State of the Map conference was held, there were over 50,000 registered contributors; by March 2009 there were 100,000 and by the end of 2009 t here were nearly 200,000.
    • Note that not all registered contributors actually contribute to the map - in March 2008 approximately 10% of the registered user s were contributing to the map data each month
  • 6. NaturNet Plus Technology
    • The initial map data was all built from scratch
      • volunteers performed systematic ground surveys using a handheld GPS unit s and a notebook s or a voice recorder s
    • Collected d ata were then entered into the OpenStreetMap database from a computer
    • More recently the availability of aerial photography and other data sources from commercial and government sources has greatly increased the speed of this work and has allowed land-use data to be collected more accurately.
    • When large datasets are available a technical team will manage the conversion and import of the data.
  • 7. NaturNet Plus Licencing
    • OpenStreetMap data is published under an open content licen c e, with the intention of promoting free use and re-distribution of the data (both commercial and non-commercial).
    • The currently used licen c e is the Creative Commons Attribution-Share Alike 2.0 licence
      • however legal investigation work and community consultation is under-way to re-license the project under the Open Database Licen c e (ODbL) which is more suitable for a map dataset

  • 9. NaturNet Plus Integration of OSN into applications
